IMPROVEMENT IN OASKS, BARRELS, sbo.

Specification forming part ofLetters Patent No. 58,449, dated October 2,1866.

To all whom zt may concern:

Be it known that I, JOSHUA MERRILL, of the city of Boston, in the countyof "Suffolk and VState of Massachusetts, have invented certain new anduseful Improvements in Casks, Barrels, and Kegs suitable for holding andtransporting liquids 5. and I do hereby declare that the following is afull and correct description thereof, reference being had to the annexeddrawings, and to the letters of reference thereon.

My said invention consists in protecting the joints of ordinary casks,barrels, and kegs suitable for holding and transporting petroleums,alcohol,and similar tluids against leakage by cernenting them togetherwith glue or other similar gelatinous cement applied to said joints whenthe staves and head pieces are separated or before they are puttogether.

The drawings show acask cemented by glue at the joints.

Figure lis a topvview of the cask; Fig. 2, a cross-section; Fig. 3, avertical section through the heads and strives; Fig. 4, a section of astave.

In carrying out my invention, I take the staves a and head-pieces el ofthe cask after they have been properly made and plainjointed, and applyhot glue to the joints b by dipping or by a brush, and then at onceproceed to set them up. "If the staves have been properly made andjointed they can be trussed and the heads put in before the glue sets,esA

pecially if the staves andheads are from an old cask,or, if new, arebent and crozed before setting up. A

The driving up of the hoops forces the glue into the pores of thejoints, imparting great strength to the cask when the glue sets, besidesresisting the leakage of petroleums, alcohol, and liquids that do notdissolve glue.

The casks made as above described may be coated inside by a coating ofglue or shellac, according to the liquid the cask is designed for. Thecoating ofthe inside is well known and not necessary to be described,except to say that it may readily be done with glue by pouring into the'cask a few gallons of hot glue solution; and then, by putting in thebling tight and rolling the cask about, the air within, being heated bythe hot glue, forces it into the pores of the interior surface of theheads and staves.

I claim- As of my invention and improvement in casks, barrels, andkegs,incombination with the joints of a cask suitable for holding andtransporting liquids, having the common straight or plain joints, acoating or stuffing of glue or similar gelatinous cement applied to thejoints before putting the cask together, substantially as described.
